Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-humidity, low-temperature storage suitable for efficiently using the storage volume of the storage.

[0002]

2. Description of the Related Art A high-humidity low-temperature storage is intended to indirectly cool a storage chamber formed inside a heat-insulating box and to store stored items while keeping the storage chamber high in humidity.

FIG. 4 is a front view showing a general structure of a high humidity and low temperature storage of this kind. The high-humidity / low-temperature storage 1 includes an upper door 2a for the upper storage room and a lower door 2b for the lower storage room,
Each of these can be opened and closed by the handles 3a and 3b. A display unit 4 and a display plate 5 are attached to the upper portion of the high-humidity / low-temperature storage 1, and a drain hose 6 is provided to the lower portion. A plurality of net shelves and the like are arranged in the storage in order to efficiently and efficiently store a large amount of stored items. In this case, the net shelves are often arranged on the bottom floor of the storage. ..

For example, FIG. 5 is a schematic cross-sectional view taken along the line AA of FIG. 4, showing a heat insulating box 7 and an inner box 8, a duct 9 formed by these as a flow path for a cooling medium, and an inner box 8. The space formed by the storage chamber 10 is used as a storage chamber 10, and a net rack 12 is arranged on the bottom 11 of the storage chamber 10 as shown in the figure.
In the net shelf 12, a plurality of bars 12b are arranged in a grid pattern in a vertical direction and a horizontal direction on a rectangular peripheral frame 12a.
On the peripheral frame 12a of the net rack 12, a guard portion 12c for preventing the fall of stored items is formed upright.

Further, a plurality of net shelves 12 are further placed in the storage chamber 10 by shelf receivers provided upright on the inner box 8.

[0006]

However, if the net rack 12 having the structure described with reference to FIG. 5 is placed on the bottom floor 11, there is a problem that dew condensation water adheres to the stored material.

That is, in the high-humidity low-temperature storage 1, since the inner box 8 serves as a cooling surface, the temperature is lower than the internal temperature of the storage chamber 10, and dew condensation water is always attached to the surface of the inner box 8. In many cases, condensed water is collected on the bottom floor 11. Therefore, in the conventional net shelf 12 simply placed on the bottom floor 11,
There is a problem that the stored material gets wet with the dew condensation water of the bottom 11 and affects the quality of the stored material. Further, the net shelves 12 arranged in the refrigerator may move to come into contact with the back surface or both side surfaces of the inner box 8, and the condensed water of the inner box 8 may adhere to the stored items.

Therefore, an object of the present invention is to provide a high-humidity low-temperature storage in which dew condensation water does not adhere to stored items even if a net rack is placed on the bottom surface of the storage chamber.

[0009]

DISCLOSURE OF THE INVENTION According to the present invention, a duct for circulating a cooling medium in a space between a heat insulating box having an opening at the front surface which is opened and closed by a heat insulating door and an inner box provided inside the heat insulating box. And the space formed by the inner box is used as a storage room for accommodating stored items, and a plurality of shelves are erected on the inner box and the net shelves are placed on the shelves to store the storage room. In a high-humidity and low-temperature storage having a configuration in which a plurality of stages of net shelves are arranged on the bottom surface of the inner box and the net shelves are also arranged on the bottom of the inner box, the net shelves are provided in the peripheral frame of the net shelves and the net shelves are predetermined from the floor It is provided with a mesh shelf which is separated by a space and has a space holding member which separates the mesh shelf from the side surface of the inner box at a predetermined space.

[0010]

With the above structure, the net rack arranged on the bottom is
It is lifted up by a predetermined distance by a distance holding member provided on the net rack. This prevents the stored matter from getting wet even with the condensed water that has accumulated on the bottom floor. Further, even if the mesh rack is moved in the lateral direction, since the mesh rack is held at a predetermined interval from the inner box by the mesh rack spacing member, the stored matter will not get wet with the condensed water on the side surface of the inner box. Moreover, since the net rack can be placed on the rack receiver as it is, it is economical and becomes a high-humidity low-temperature storage that does not adversely affect the quality of stored items.
